This adjustable ruler supports dragging a cutter knife along a border in a defined distance.
The ruler is printed as two parts to be glued together with CA glue to save support material.
Glue a M3x12 threaded rod (or a screw without head) into the slider and insert a M3 nut into the fixing knob. You will need some pressure or a pre-heated nut for insertion, but then it will be reliably fixed.
